Nobody shaved a freaking hole in the side of the compressor, it's been worn there by the metal hose, it's clearly obvious, end of story.

There shouldn't be any appreciable pressure in the intake hose, but there may be a slight surge of it as the compressor bypass valve opens and dumps the boost back into the intake when you let off the gas which prevents the turbine from slowing down. If the breather hose is blowing off then it's worn or hardened to the point that it won't stay on. A zip tie is probably enough to temporarily fix it anyway.

If you haven't already, give Dave a shout. He found a harness for my

1987 740 and worked to fit my budget. I ordered the harness on Friday and I haven't yet received the harness, but I REALLY like Dave and his communication and service.

Okay---and yes, James, you are right--the hose has turned to plastic and hardened and won't stay on.

Thanks. hehe "shaved" ; ) As you see, I'm a Noob, so I'm just learning about this "inherited" car I have.
